The Consciousness Atlas is an interactive web app that visualizes more
than 450 theories of consciousness. It is based on Robert Lawrence
Kuhn's 2024 paper,
"A Landscape of Consciousness". The Atlas maps theories that address phenomenal consciousness - the
subjective feel of experience, such as the redness of red.
What the Atlas is
The Atlas is a visual reference built on Kuhn's taxonomy. It presents
the full set of theories at once so you can explore the field visually
and open any theory to read its entry, like an encyclopedia with
structured entries. Each theory entry shows a concise identity line,
conceptual ground, suggested mechanism, empirical notes, implications,
and sources.
Why this exists
Consciousness is studied across disciplines - neuroscience,
philosophy, and sometimes spiritual or anomalous-state research.
Kuhn's paper collects and organizes hundreds of theories along a
spectrum from most physical to least physical. The Atlas puts that
organization into a visual form so readers, students, and researchers
can quickly see how different positions relate and where each theory
sits on the spectrum.
How it works
Theories are grouped into ten main categories, arranged by their
stance on the physical-to-nonphysical spectrum. Examples of categories
include Materialism, Non-Reductive Physicalism, Functionalism,
Quantum-based theories, Panpsychism, Monism, Dualism, Idealism,
Anomalous States, and Challenge Theories. The app shows the whole map
at once. Click any theory to read its structured entry, which includes
references to canonical sources and named thinkers.
Who it is for
- Students learning philosophy of mind and cognitive science
-
Researchers and lecturers looking for an at-a-glance comparative
resource
-
Journalists and writers who need a quick reference to the range of
positions
-
Curious readers who want a clear view of what people mean when they
talk about consciousness
What the Atlas does not do
The Atlas does not endorse or rank theories. It is a visualization and
reference based on Kuhn's taxonomy - collect and present, not judge.
It does not attempt to settle the hard problem of consciousness. It is
a tool for exploration and comparison.
A note from Kuhn
Kuhn explicitly states the project's purpose: "collect and categorize,
not assess and adjudicate." The Consciousness Atlas follows that
approach. The data and structure are derived from Kuhn's paper;
feedback and suggested corrections are welcome, but the app is a
visualization layer on top of Kuhn's work.
Kuhn was not involved in the design or content of the Consciousness
Atlas, other than his original paper, 'A Landscape of Consciousness,'
which is the sole source.
FAQ
What is phenomenal consciousness?
Phenomenal consciousness refers to subjective experience - the
qualitative feel of being aware, like the taste of coffee or the
redness of red.
How many theories does the Atlas include?
The Atlas visualizes over 220 individual theories, grouped into ten
broad categories.
Does the Atlas show which theory is true?
No. The Atlas presents theories neutrally. It is a map, not an
argument for any single position.
Is the Atlas academic?
The Atlas is based on an academic source - Robert Kuhn's 2024 paper,
"A Landscape of Consciousness" - and links to canonical sources
where available.
Summary
The Consciousness Atlas is a straightforward visualization tool: it
presents Kuhn's taxonomy as a single, explorable map and lets users
open individual theory entries to read structured, referenced
summaries. It is designed to make this complex field easier to survey
and to serve as a practical reference.

Sreedharan’s Affective Survival Theory
Consciousness as Felt Affect Selected for Survival
Sreedharan argues that consciousness evolved by natural selection as a system of felt affective prioritization. Pain, fear, hunger, and pleasure tag stimuli with survival relevance, which sharpens memory, attention, and flexible behaviour, so the fact that experience feels like something is itself the adaptive advantage.
Shaji Sreedharan
What consciousness is
Consciousness is the felt capacity to encode survival-relevant experience: affective states that weight what an organism perceives with urgency and meaning.
Mind and body
Felt states are biological functions of organisms. Sreedharan presents the theory as an account of why consciousness evolved, compatible with physical theories, whether neuronal or quantum, that explain how it is produced.
Mechanism
Affective modulation: felt emotion weights sensory input by survival relevance, which raises the salience of some memories, drives approach or avoidance, and regulates attention.
Core claims
- Mental traits, like physical ones, persist in lineages only if they confer a survival or reproductive advantage.
- Emotionally charged memories are retained better and shape future behaviour more, a finding Sreedharan draws from work by LeDoux and Phelps.
- Consciousness is defined by felt encoding of survival-relevant experience, not by reasoning or language, which fits evidence of affective consciousness in non-human animals.
Criticisms
Showing that affect improves memory and behaviour does not show that the felt quality, as opposed to the underlying neural signalling, does the work. Relabelling the hard problem as a ‘hard advantage’ explains why feeling might be useful, not why it exists.
Implications
- AI consciousness: Uncertain
- Consciousness here is tied to evolved affective systems serving organismic survival; whether an artificial system without such stakes could feel is not addressed.
- Survival beyond death: No
- Since consciousness is a biological function of living organisms, it follows from the view that it does not survive the organism's death.
- Meaning and purpose: Humanistic only
- Sreedharan calls consciousness nature's strategy for intelligent survival, a biological purpose without cosmic teleology.
